[2/2] asterixdb git commit: [ASTERIXDB-2476][FUN] Support array
slicing in SQL++
Posted by dl...@apache.org.
[ASTERIXDB-2476][FUN] Support array slicing in SQL++
- user model changes: yes
- storage format changes: no
- interface changes: no
Details:
- Added array_slice function. 2 functions were added, one that
accepts 2 arguments and the other accepts 3 arguments. The
arguments are (list, start, end) respectively.
- Added array_slice function test cases.
- Array slice syntax and documentation will be added in subsequent
changes.

+ *
+ * It throws an error at compile time if the number of arguments is greater than {@code 3} or less than {@code 2}.
+ *
+ * {@code NULL} is returned if:
+ * - {@code array} is not an array.
